Stop relying on messy notes or complex spreadsheets – track everything accurately in one secure, easy-to-use app. Comprehensive Peptide Inventory Management: Log Any Peptide: Maintain a detailed database of all your compounds – from research peptides and GHRP/GHRH analogs (like CJC-1295 or Ipamorelin) to healing peptides and GLP-1s. Track Critical Vial Data: Record concentration (mg/mcg), units, vial size (ml), diluent (e.g., BAC water), date, storage conditions (fridge/freezer), source, batch number, and expiration dates. Essential for consistency and safety across all peptide protocols.

Perfect for managing complex peptide stacks or cycles. Intelligent Injection Site Rotation: Smart Site Tracking: Maintain a personalized map of injection sites with customizable rest periods for optimal absorption and tissue recovery. Rotation Recommendations: Receive intelligent suggestions for your next injection site based on usage history and proper rotation patterns.
